Abstract
OBJECTIVE
This retrospective study aimed to investigate the factors influencing the occurrence of neutropenia in patients with endometrial cancer (EC) following adjuvant chemoradiotherapy (CRT).
METHODS
Retrospective analysis of EC patients who underwent adjuvant CRT from January 2012 to June 2023 in the Department of Gynecology and Oncology of the First Affiliated Hospital of Shandong First Medical University. Neutropenia was defined as an Absolute Neutrophil Count (ANC) of peripheral blood neutrophils below 2 × 109/L. Factors affecting neutropenia in EC patients treated with CRT using Generalized Estimating Equation (GEE), and Logistic regression was used to further analyze the effect of adding radiotherapy to different chemotherapy cycles on neutropenia, so that patients receive optimal adjuvant CRT while the risk of neutropenia is appropriately controlled.
RESULTS
A total of 144 patients met the inclusion criteria. They underwent 330 cycles of adjuvant chemotherapy, of whom 96 (66.7%) developed neutropenia, which occurred 140 times. The results of one-way GEE analysis showed that before CRT, White Blood Cell (WBC) (OR = 0.827; 95%CI, 0.701-0.976), ANC (OR = 0.749; 95%CI, 0.586-0.957), Absolute Monocyte Count (AMC) (OR = 0.047; 95%CI, 0.008-0.283), Blood Urea Nitrogen (BUN) (OR = 0.857; 95%CI, 0.741-0.991), platinum and docetaxel (platinum/docetaxel) dosing regimen (OR = 2.284; 95%CI, 1.130-4.618) were associated with neutropenia with adjuvant CRT for EC (p < 0.05), results of multifactorial GEE analysis showed that before adjuvant CRT ANC (OR = 0.552; 95%CI, 0.973-2.231), AMC (OR = 0.047; 95%CI, 0.004-0.052), platinum/docetaxel (OR = 2.437; 95%CI, 1.087-5.464) were an independent influence on neutropenia in adjuvant CRT for EC (p < 0.05). Multifactorial Logistic regression shows addition of radiotherapy to the first cycle of chemotherapy (OR = 4.413; 95%CI, 1.238-18.891) was an independent influence of neutropenia (p < 0.05).
CONCLUSIONS
Patients with low pre-CRT ANC and AMC, platinum/docetaxel dosing regimens need to be closely monitored during each cycle of CRT. Also, the concurrent addition of radiotherapy should be avoided during the first cycle of chemotherapy.
